Assessment of dural invasion in complex cases operated on by collaborative efforts of neurosurgery and otolaryngology for pathologies associated with the frontal sinus

Purpose: The aim of this study was to evaluate the common interventions performed by neurosurgery and otolaryngology in dural invasion in frontal sinus related pathologies. Materials and Methods: A comprehensive study involving 45 patients who underwent surgical interventions for frontal sinus-associated pathologies between January 2018 and July 2023 was conducted collaboratively by otorhinolaryngology and neurosurgery departments. Patient data, including demographics, pathology types, and surgical approaches, were collected from medical records, surgical reports, imaging studies, and videos. Interdisciplinary surgical teams executed tailored interventions with documented techniques. Results: Among 45 patients, 31 were female (68.8%) with a mean age of 44. Posterior wall defects were detected in 13 (28.8%) patients, and intervention was necessary for only 8 of them. Among the 8 (17.7%) patients with identified dural invasion, pathological dural tissue was excised, and duraplasty was performed in 5 (11.1%) cases. There were no neurological complications observed in patients during the postoperative period. Conclusion: Despite limitations, the findings contribute to evolving knowledge and highlight the need for prospective studies to optimize patient care strategies.
